Cabergoline Patient Handout
Cabergoline For the Patient: Cabergoline Other names: DOSTINEX® • Cabergoline (ca-BERG-go-leen) is used to treat cancers that cause the body to produce too much of a hormone called prolactin. Cabergoline helps decrease the size of the cancer and the production of prolactin. It is a tablet that you take by mouth. • Tell your doctor if you have ever had an unusual or allergic reaction to bromocriptine or other ergot derivatives, such as pergoline (PERMAX®) and methysergide (SANSERT®), before taking cabergoline. • Blood tests and blood pressure measurement may be taken while you are taking cabergoline. The dose of cabergoline may be changed based on the test results and/or other side effects. • It is important to take cabergoline exactly as directed by your doctor. Make sure you understand the directions. Take cabergoline with food. • If you miss a dose of cabergoline, take it as soon as you can if it is within 2 days of the missed dose. If it is over 2 days since your missed dose, skip the missed dose and go back to your usual dosing times. • Other drugs such as azithromycin (ZITHROMAX®), clarithromycin (BIAXIN®), erythromycin, domperidone, metoclopramide, and some drugs used to treat mental or mood problems may interact with cabergoline. Tell your doctor if you are taking these or any other drugs as you may need extra blood tests or your dose may need to be changed. Check with your doctor or pharmacist before you start or stop taking any other drugs. • The drinking of alcohol (in small amounts) does not appear to affect the safety or usefulness of cabergoline. -
Drugs Affecting Milk Supply During Lactation

Biased Ligands Differentially Shape the Conformation of The
International Journal of Molecular Sciences Article Biased Ligands Differentially Shape the Conformation of the Extracellular Loop Region in 5-HT2B Receptors Katrin Denzinger, Trung Ngoc Nguyen, Theresa Noonan, Gerhard Wolber and Marcel Bermudez * Institute of Pharmacy, Freie Universität Berlin, Königin-Luise-Strasse 2-4, 14195 Berlin, Germany; [email protected] (K.D.); [email protected] (T.N.N.); [email protected] (T.N.); [email protected] (G.W.) * Correspondence: [email protected] Received: 22 November 2020; Accepted: 18 December 2020; Published: 20 December 2020 Abstract: G protein-coupled receptors are linked to various intracellular transducers, each pathway associated with different physiological effects. Biased ligands, capable of activating one pathway over another, are gaining attention for their therapeutic potential, as they could selectively activate beneficial pathways whilst avoiding those responsible for adverse effects. We performed molecular dynamics simulations with known β-arrestin-biased ligands like lysergic acid diethylamide and ergotamine in complex with the 5-HT2B receptor and discovered that the extent of ligand bias is directly connected with the degree of closure of the extracellular loop region. Given a loose allosteric coupling of extracellular and intracellular receptor regions, we delineate a concept for biased signaling at serotonin receptors, by which conformational interference with binding pocket closure restricts the signaling repertoire of the receptor. Molecular docking studies of biased ligands gathered from the BiasDB demonstrate that larger ligands only show plausible docking poses in the ergotamine-bound structure, highlighting the conformational constraints associated with bias. This emphasizes the importance of selecting the appropriate receptor conformation on which to base virtual screening workflows in structure-based drug design of biased ligands. -
Ergot Alkaloids As Dopamine Agonists: Comparison in Two Rodent Models

ANLEZARK, C. PYCOCK and B. MELDRUM, Ergot alkaloids as dopamine agonists: comparison in two rodent models, European J. Pharmacol. 37 (1976) 295-302. A series of ergot alkaloids, together with the DA agonists apomorphine and piribedil, were tested for protec- tive effects against audiogenic seizures in an inbred strain of mice (DBA/2) and for induction of circling behaviour in mice with unilateral destruction of one nigrostriatal DA pathway. The order of potency against audiogenic sei- zures was apomorphine> ergocornine> bromocryptine > ergometrine> LSD> methysergide > piribedil while that observed in the rotating mouse model was apomorphine> ergometrine> ergocornine> brornocryptine > piribedil. LSD caused only weak circling behaviour even when administered in high doses (> 1 mg/kg). Methyser- gide was ineffective. Prior administration of the neuroleptic agent haloperidol blocked the effect of DA agonists and of ergot alkaloids in both animal models.

The scope and chemoselectivity of this tandem process is broad and it tolerates many functional groups and classes of allylic alcohol starting material. The diastereoselectivity of the Claisen rearrangement was investigated with moderate to excellent diastereomeric selectivity for the formation of the γ,δ-unsaturated α,α-dibromo esters. The product α,α-dibromo esters are also shown to be valuable chemical building blocks. They were used in the synthesis of the ynolate reaction intermediate, as well as other carbon–carbon bond- forming reactions. Highly functionalized lactones were also shown to be simply prepared from the γ,δ-unsaturated α,α-dibromo ester starting materials formed via the Cliasen rearrangement. ii A phosphine-catalyzed [4 + 2] annulation of imines and allenoates is also investigated herein. -

What Dostinex is and what it is used for - Dostinex contains the active ingredient cabergoline. This medicine belongs to a class of medicines called ‘dopamine agonists’. Dopamine is produced naturally in the body and helps to transmit messages to the brain. - Dostinex is used to stop breast milk production (lactation) soon after childbirth, stillbirth, abortion or miscarriage. It can also be used if you do not want to continue to breast-feed your baby once you have started. - Dostinex can also be used to treat other conditions caused by hormonal disturbance which can result in high levels of prolactin being produced. This includes lack of periods, infrequent and very light menstruation, periods in which ovulation does not occur and secretion of milk from your breast without breast-feeding. -
Cabergoline (Bovine)
22 August 2014 EMA/CVMP/656490/2013 Committee for Medicinal Products for Veterinary Use European public MRL assessment report (EPMAR) Cabergoline (bovine) On 19 June 2014 the European Commission adopted a Regulation1 establishing maximum residue limits for cabergoline in bovine, valid throughout the European Union. These maximum residue limits were based on the favourable opinion and the assessment report adopted by the Committee for Medicinal Products for Veterinary Use (CVMP). Cabergoline is intended for use in dairy cows for the reduction of udder involution duration during the drying-off period in the dairy cow and is administered as a single intramuscular injection. CEVA Santé Animale submitted an application for the establishment of maximum residue limits to the European Medicines Agency on 21 September 2012. Based on the data in the dossier, the CVMP recommended on 12 December 2013 the establishment of maximum residue limits for cabergoline in bovine species. Subsequently the Commission recommended on 27 March 2014 that maximum residue limits in bovine species are established. This recommendation was confirmed on 17 April 2014 by the Standing Committee on Veterinary Medicinal Products and adopted by the European Commission on 19 June 2014. 1 Commission Implementing Regulation (EU) No 677/2014, O.J.
